2 Claims.

This invention relates to improvements in looks adapted to be used inconnection with electric meters, and so constructed that when onceapplied in order to remove the lock the hasp thereof must be broken.

It is the object of this invention to provide a hasp which when brokencannot be repaired or replaced except by a similar hasp, composed ofsimilar material and similarly constructed.

It is particularly the object of this invention to provide, inconnection with a lock case, a hasp composed of a pair of flat legswhich cannot be rotated in the passageway provided therefor in the case,and therefore cannot be removed from the case when once broken.

These and other advantages will appear from the following descriptiontaken in connection with the drawing.

It will be understood that the hasp may be of any thickness so long asat least one wall is flat. For instance, the hasp may be square insection when it is desired to strengthen the metal of the hasp. In usingthe word rectangular I am referring generically to any flat-facedstructure,

; whether square or oblong.

Referring to the drawing:

Figure 1 is a side elevation of the lock with the hasp associatedtherewith in looking position.

Figure 2 is a top plan view of the lock.

Figure 3 is a side elevation of the lock, showing one of the sidesremoved.

Figure 4 is a righthand view of the lock shown in Figure 1.

Figure 5 is a lefthand view of the lock shown in 351 Figure 1. I

Figure 6 is a section on the line 6-6 of Figure 1.

Figure '7 is a bottom plan view of the lock.

Figure 8 is a view of the hasp with one part broken 01f.

The case constituting the body of the lock is composed of a side 1 and aside 2, each of which has a hole 3 therein through which a rivet 4 ispassed for uniting the two sides into a single unitary case. This rivethas on each end a head 5,

V which fits in a countersink 6 in the outer surface of each side. Asshown in Figures 6 and 7, one head is enlarged.

The side 2 on its upper edge has therein a notch 7 adapted to receive aflange 8 on the upper edge of the side 1. These flanges and notchesprevent displacement of one side with relation to the other. The side 2also has on one lateral edge a notch 9, into which fits a projection 10on the other side 1, as shown in Figures 4 and 5.

Adjacent one edge of the case and extending therethrough is a passageway11, while adjacent the other edge of the case is a similar passageway12. At the upper end of the passageway 11 there is formed in the case anenlargement 13, which forms a pocket 14. These passageways are adaptedto receive legs 16 and 20 of a hasp 15.

On the upper end of the leg 16 is a shoulder 17 adapted to rest in thepocket 14 when the legs are positioned within the passageways. There isalso provided in the leg 16 a groove 18 extending entirely around theleg, which weakens the leg and makes it more easily broken. There isalso provided in this leg, below the groove 18 on one edge thereof, anotch 19, the purpose of which will be later explained. The other leg 20is connected to the upper part of the hasp by means or" an arcuatemember 21, which has therein a plurality of grooves 22, similar to thegroove 18. There is also a groove in the leg 20.

In the leg 20, opposite the notch 19, is a notch 23. These notches formshoulders adapted to be engaged by the ends 25 of a spring 24, coiledaround the rivet 4.. As shown in Figure 3, the ends of this spring 24are engaging the lower shoulders formed by the notches 19 and 23 andtend to hold the hasp in a position such as that shown in Figure 3.

In order to remove the lock from any article to which it is attached thehasp must be broken at some of the weak points produced by the grooves.When the hasp is thus broken the leg 16 cannot be removed from the case.The spring and the shoulder 1'7 prevent longitudinal movement of theleg, and the rectangular shape of the leg prevents its rotation. The leg20 cannot be rotated so as to displace the end of the spring from thenotch 23. This leg can only be removed against the tension of the spring24, which is sufiiciently strong to require a good deal of force appliedto the leg to move it longitudinally in a downward direction forremoving it from the case. Each of the passageways 11 and 12 isrectangular in shape, having parallel opposite walls to receive thesimilarly shaped legs of the hasp so that the legs cannot rotate in thepassageways.

In Figure 8 one-half of the hasp is shown, the other half having beenbroken away.

It will be understood that it is desired to comprehend within thisinvention such modifications as come within the scope of the claims andthe invention.

Having thus fully described the invention, what is claimed as new anddesired to be secured by Letters Patent, is:

1. In a lock, an apertured case having square openings therein, a hasphaving fiat legs mountable therein, said legs being connected by a partof the hasp perpendicular to one leg and arcuate at the other leg, acommon spring member having downwardly and laterally extending legspivotally supported in said case with its ends projecting into thepassageways for the legs of the hasp, said hasp legs having notchestherein for receiving said spring ends to prevent the withdrawal of thehasp, a socket on said case around one end of one of said apertures, anda shoulder on said hasp adjacent the perpendicular part thereof adaptedto seat within said socket.
